Cisco Cisco 12000 Series 12-Port DS3 Line Card

The 1-Port 10-Gigabit Ethernet line card provides the supported Cisco 12000 Series Routers with one 
optical 802.3ae 10-Gigabit Ethernet interface. This interface provides a high-speed connection to other 
network devices, such as Cisco 12000 Series Routers, or to other routers or layer-2 or layer-3 switches 
that support 10-Gigabit Ethernet interfaces. 

 shows the front view of the line card. 

The port on the front panel of the line card is port number 0. This port uses a hardwired laser optical 
transceiver to provide a 10-Gigabit Ethernet optical interface. The transceiver consists of two optical 
interfaces—laser transmit (TX) and laser receive (RX)—that use SC connectors.

Next to the port on the line card are three green LEDs, aligned vertically and labeled from top to bottom 
as follows: LINK, ACTIVE, and RX FRAME.
